usefulL Improvements in .Press-Rolls, of'v which the following is aspecification.'

This linvention relates to press rolls, -for use on expressingpresses'employed in -separating the juice from fruit and the like,

the object of the invention being to provide an improved form of pressand rollerwhich will not shrink and swell under the influence of theconstant wetting and drying and which will not oxidize' or corrode-andwhich will not color or injuriously affect the uice. l

J A further object of the invention is to provide a roll Which will makeproper allowance for the usual belt or carrier so as not to subjectlsaid belt or carrier to pressure except when operating upon the fruit orother material. j.

Vith the abo-ve and other objects in view, the invention consists inthenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.-

In the accompanying drawvingsr-E`igure 1 is a perspective view of apairofrolls embodying the present invention. Fig. 2 is an enlargeddiametrical section' through one end of the same, illustrating theconstructio-n thereof. Fig. 3 is a cross section 35 through one of t-herolls.

In the preferred embodiment of the invention, each of the rollscomprises a shaft l, oppositely arranged heads 2 mounted on the shaftand secured together -by rods 3, 40 any desired number of which may beemployed. e Y The headsare provided at their outer peripheries withinwardly extending outer rims or flanges 4 and they are further pro--vided with inner flanges 5 which form the support for a form 6ordinarily composed of wood or strips of Wood resting on their Aends onthe flanges 5 of the heads as indicated in Figs; 2 and 3. The workingface of each roll is composed of a body of concrete 7 in which is areinforce 8 shown by preference in the form of meshed wire fabric. Theconcrete body is molded around the form 6 and a portion of said body isconfined within the marginal rims or flanges .A' 'Specification ofLetters Patent.

Patented Oct. 24k, 19th of the heads 2 as V'clearly shown in Fig.` 2

wherein it' will also be observed that the rim or flange is of greaterdiameter Athan the concrete body of .therolh the object being to provideeach of the1 rolls shown in Figs. l

and 2 with marginal rims or flanges whichA will bear against each otherand prevent the concrete bodies or working faces of the rolls fromtouching each other and causing unnecessaryxpressure on the travelingcarrier or'belt (not shown), which travels between the rolls inexpressing presses of the class referred to. The construction alsoprovides the necessary 'space between the working faces of thev rollstop-admit of the free passage between the same of the carrier or beltand no pressure is applied to such carrier or belt except `when thelatter contains fruit .or other material from, which the juice is to beexpressed by the action of the press rolls.

The advantage of using a concrete working face for the press rollsresides in the fact that said working face will notA shrink and swell bythe constant wetting and drying thereof as in the case of wooden rolls;also the concrete working faces will not oxidize rust or co'rrode likeiron or other metal rolls; further, the concrete working surface willnoteolor or discolor or injuriously affect the juice.

It will be understood that the distance between the end flanges 4 isequal to or slightly greater than the extreme width of the belt or apronor carrier so that said belt or apron will not be caught between thebearing portions of the rolls formed by said flanges 4. I claim z* 1. Aroll for expressing presses comprising oppositely arranged heads each ofsaid heads provided with inwardly extending inner and outer peripheralflanges, a wooden form arranged upon the inner flange of the heads, rodsconnecting said heads,and concrete cylindrical body formed upon thewooden form and of less diameter than the said heads, the said bodyhaving a reinforce formed therein.

2. A roll for expressing vpresses consisting of a support, oppositelyarranged heads .upon the support, said heads provided at theirperipheries with inner and outer a-nges, a wooden form arranged upon theinner flanges of the heads,- a concrete cylin- 110 drcal body formedupon thea-wooden form and ofless diameter than theheads, vanda reinforceembedded within the conoret'e body, and rods connecting the headstogether and to the body of thei'oll,

l 3. A roll for expressing'presses consisting of a shaft, circular headsarranged'pon the shaft and providedvat their peripheries with inwardlyextendinginner and outer angea 'a wooden form arranged upon' innerflanges, a concrete cylindrical body formed upon the wooden forml andprovided with a meshed wire fabric; said body being of less diameterthan the heads, and rods extending through thewooden form and con- 15necting the heads together and to the body of the roll.

` In testimony whereof I -aiiix my signature in presence of twowitnesses.
